I have seen people use this method for SVG-based NFTs:
function p5jsToImageURI(){
string memory baseURL = "data:image/svg+xml;base64,PUT-BASE64-HERE"
}
But, since I don't want to generate a fixed image how can I use my p5js script (that looks slightly different each time the js code runs)? Is there a way to just somehow pass the seed to my script and the script with the seed passed to it is stored on-chain?
var img,inpt,div
function convertImgToDataURLviaCanvas(url, callback, outputFormat){
var img = new Image();
img.crossOrigin = 'Anonymous';
img.onload = function(){
var canvas = document.createElement('CANVAS');
var ctx = canvas.getContext('2d');
var dataURL;
canvas.height = this.height;
canvas.width = this.width;
ctx.drawImage(this, 0, 0);
dataURL = canvas.toDataURL(outputFormat);
callback(dataURL);
canvas = null;
};
img.src = url;
}
function convertFileToDataURLviaFileReader(url, callback){
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function () {
callback(reader.result);
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', url);
xhr.send();
}
function img2b64(imagefile){
var imageUrl = imagefile;
var convertType = 'Canvas';
var convertFunction = convertType === 'FileReader' ? convertFileToDataURLviaFileReader : convertImgToDataURLviaCanvas;
convertFunction(imageUrl, function(base64Img){
code='foto = "'+base64Img+'";'
inpt.value(code)
div.html('<img src="'+base64Img+'">');
});
}
function setup() {
but = createButton("CONVERT");
but.mousePressed(function () {
img2b64('nature100b.jpg');
});
inpt = createP('');
inpt = createElement("textarea",'');
inpt.elt.rows = 5;
inpt.elt.cols = 50;
div = createDiv('');
}
